Chapter 2: System Safety
Chapter 2
System Safety
2-1 Overview
This chapter provides a quick setup checklist to get your chassis up and running.
Following the steps in order given should enable you to have your chassis set up
and operational within a minimal amount of time. This quick setup assumes that you
are an experienced technician, famailiar with common concepts and terminology.
2-2 Warnings and Precautions
You should inspect the box the chassis was shipped in and note if it was damaged
in any way. If the chassis itself shows damage, le a damage claim with carrier
who delivered your system.
Decide on a suitable location for the rack unit that will hold that chassis. It should
be situated in a clean, dust-free area that is well venilated. Avoid areas where heat,
electrical noise and eletromagnetic elds are generated.
You will also need it placed near at least one grounded power outlet. When cong-
ured, the SC808 chassis includes one power supply.
2-3 Preparing for Setup
The SC808 Chassis includes a set of rail assemblies, including mounting brackets
and mounting screws you will need to install the systems into the rack. Please read
this manual in its entirety before you begin the installation procedure.
2-4 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC808 from damage:
Be aware of the locations of the power on/off switch on the chassis as well•
as the room’s emergency power-off switch, disconnection switch or electrical
outlet. If an electrical accident occurs, you can then quickly remove power from
the system.
Do not work alone when working with high voltage components.•

SC808 Chassis Manual
2-2
Power should always be disconnected from the system when removing or in-•
stalling main system components, such as the serverboard, memory modules
and the DVD-ROM and oppy drives (not necessary for hot swappable drives).
When disconnecting power, you should rst power down the system with the
operating system and then unplug the power cords from all the power supply
modules in the system.
When working around exposed electrical circuits, another person who is fa-•
miliar with the power-off controls should be nearby to switch off the power, if
necessary.
Use only one hand when working with powered-on electrical equipment. This•
is to avoid making a complete circuit, which will cause electrical shock. Use
extreme caution when using metal tools, which can easily damage any electrical
components or circuit boards they come into contact with.
Do not use mats designed to decrease electrostatic discharge as protection from•
electrical shock. Instead, use rubber mats that have been specically designed
as electrical insulators.
The power supply power cord must include a grounding plug and must be•
plugged into grounded electrical outlets.
Serverboard battery: CAUTION - There is a danger of explosion if the onboard•
battery is installed upside down, which will reverse its polarities This battery
must be replaced only with the same or an equivalent type recommended by
the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
Please handle used batteries carefully. Do not damage the battery in any way;•
a damaged battery may release hazardous materials into the environment. Do
not discard a used battery in the garbage or a public landll. Please comply
with the regulations set up by your local hazardous waste management agency
to dispose of your used battery properly.
DVD-ROM laser: CAUTION - this server may have come equipped with a•
DVD-ROM drive. To prevent direct exposure to the laser beam and hazardous
radiation exposure, do not open the enclosure or use the unit in any uncon-
ventional way.

2-3
Chapter 2: System Safety
2-5 General Safety Precautions
Keep the area around the chassis clean and free of clutter.•
Place the chassis top cover and any system components that have been re-•
moved away from the system or on a table so that they won’t accidentally be
stepped on.
While working on the system, do not wear loose clothing such as neckties and•
unbuttoned shirt sleeves, which can come into contact with electrical circuits or
be pulled into a cooling fan.
Remove any jewelry or metal objects from your body, which are excellent metal•
conductors that can create short circuits and harm you if they come into contact
with printed circuit boards or areas where power is present.
After accessing the inside of the system, close the system back up and secure•
it to the rack unit with the retention screws after ensuring that all connections
have been made.
2-6 System Safety
Electrostatic discharge (ESD) is generated by two objects with different electrical
charges coming into contact with each other. An electrical discharge is created to
neutralize this difference, which can damage electronic components and printed
circuit boards. The following measures are generally sufcient to neutralize this
difference before contact is made to protect your equipment from ESD:
Do not use mats designed to decrease electrostatic discharge as protection from•
electrical shock. Instead, use rubber mats that have been specically designed
as electrical insulators.
Use a grounded wrist strap designed to prevent static discharge.•
Keep all components and printed circuit boards (PCBs) in their antistatic bags•
until ready for use.
Touch a grounded metal object before removing any board from its antistatic•
bag.
Do not let components or PCBs come into contact with your clothing, which may•
retain a charge even if you are wearing a wrist strap.

SC808 Chassis Manual
2-4
Handle a board by its edges only; do not touch its components, peripheral chips,•
memory modules or contacts.
When handling chips or modules, avoid touching their pins.•
Put the serverboard and peripherals back into their antistatic bags when not•
in use.
For grounding purposes, make sure your computer chassis provides excellent•
conductivity between the power supply, the case, the mounting fasteners and
the serverboard.

System Interface
4-1 Overview
There are several LEDs on the control panel and drive carriers to keep you con-
stantly informed of the overall status of the system. SC808 models include two front
panels that control two semi-independent system.
This chapter explains the meanings of all LED indicators and the appropriate re-
sponse you may need to take.

SC808 Chassis Manual
4-2
4-2 Control Panel Buttons
There are two push-buttons located on the front of the chassis. These are (in order
from left to right) a reset button and a power on/off button.
Reset: The reset button is used to reboot the system.•
Power: The main power switch is used to apply or remove power from the power•
supply to the server system. Turning off system power with this button removes
the main power but keeps standby power supplied to the system. Therefore,
you must unplug system before servicing.
4-3 Control Panel LEDs
The control panel located on the front of the SC808 chassis has ve LEDs. These
LEDs provide you with critical information related to different parts of the system.
This section explains what each LED indicates when illuminated and any corrective
action you may need to take.
Universal Information LED: The Universal Information LED is used to indicate•
fan failure, power failure, overheat condition, or to identify the unit within a large
rack installation. The feature requires a motherboard that supports the Universal
Information LED.
When this LED blinks red quickly, it indicates a fan failure and when blinking red
slowly a power failure. This LED will be blue when used for UID (Unit Identier).
When on continuously red, it indicates an overheat condition, which may be caused
by cables obstructing the airow in the system or the ambient room temperature
being too warm. See the table below for descriptions of the LED states
